Apple really unleashed the spoofs and goofs when the care instructions were spotted online for its new Credit card. Of particular note were warnings against contact with denim and leather— common materials for people who own wallets and/or wear pants.

In the intervening week and change, I’m sure more than one entrepreneur had the thought of targeting those very specific parameters. Take Pittsburg-based KerfCase, which is offering this $39 wooden card case with a pop up feature for the card. It looks nice, I suppose. I mean, it’s the nicest wooden Apple Card case I’ve seen all afternoon (though I’m bound to get 50 more in my inbox after posting this).

Founder Benjamin Saks notes that the project started out a bit tongue-in-cheek, but eventually it became a real project and turned out pretty well. I understand that penicillin was discovered in similar fashion.
